It is a principal part sectional drawing of a wall structure.

In the figure, 11 is an outer wall and 31 is the outer wall 1.
The pins 31 are arranged so as to project outward at a plurality of positions, and the pins 31 are fixed to the outer wall 11 by welding. Further, 34 is rock wool as a heat insulating material arranged on the outer side of the outer wall 11, and the rock wool 34 is pressed against the outer wall 11 with the pin 31 fixed to the outer wall 11. The tip of the pin 31 penetrates the rock wool 34 and is projected. A plurality of speed washers 32 are arranged on the outer surface of the rock wool 34, and the speed washers 32 are fixed to the pins 31 to hold the rock wool 34 in place.

Further, anchors 71 are provided so as to project outward at a plurality of positions on the outer wall 11, and the anchors 71 are fixed to the outer wall 11 by welding. In this case, the anchor 71 is 90 in the vicinity of the tip.
[°] It is formed by twisted flat steel. The anchor 71 has a twist bar shape and includes a horizontal portion 72 and a vertical portion 73, and is fixed so that the vertical portion 73 is located on the outer wall 11 side.

The anchor 71 has a length such that the horizontal portion 72 projects from the outer surface of the rock wool 34 when the rock wool 34 is held by the pin 31 and the speed washer 32. Therefore, two anchors 7 are provided outside the outer surface of the rock wool 34.
A furring strip 56 is laid between the ends of the No. 1 and a corrugated outer iron plate 55 is fixed to the furring strip 56.

The furring strip 56 is made of a steel material having an L-shaped cross section, and has a horizontal portion 57 and a vertical portion 58.
The anchor 7 is formed by a bolt 61 and a nut 62 so that the horizontal portion 57 is located below the vertical portion 58.
Fixed to 1. Further, since the vibration isolator 64, 65 is disposed between the horizontal portion 57 of the furring strip 56 and the horizontal portion 72 of the anchor 71, and between the horizontal portion 72 and the nut 62, passage of high temperature gas is possible.

The bending position of the twist bar in the anchor 71 is the tip end near the connecting portion with the furring strip 56. In this way, since the anchor 71 is made of flat steel, the weight thereof is about half that of the conventional anchor 51 (see FIG. 4). Further, since only the vertical portion 73 of the anchor 71 penetrates the rock wool 34, the rock wool 3
The cutting process of 4 becomes easy.

Further, since the deformation absorbing portion 81 is formed between the horizontal portion 72 and the vertical portion 73 of the anchor 71,
When the heat of the high-temperature gas is transmitted to the outer wall 11 and the outer wall 11 thermally expands to expand the space between the anchors 71, the deformation absorbing portion 81 deforms and absorbs the thermal expansion. Therefore, the outer iron plate 55 does not come off and the outer wall 11 does not deform.

Further, since the vibration-proof materials 64 and 65 are arranged between the horizontal portion 57 of the furring strip 56 and the horizontal portion 72 of the anchor 71, and between the horizontal portion 72 and the nut 62, the exterior. It is also possible to absorb the vertical thermal expansion of the iron plate 55. Next, a second embodiment of the present invention will be described. FIG. 11 is an attachment state diagram of the anchor in the second embodiment of the present invention.

As shown in the figure, anchors 71 are provided so as to project outward at a plurality of locations on the outer wall 11, and the anchors 71 are fixed to the outer wall 11 by welding.

Further, outside the outer surface of the rock wool 34, a furring strip 56 is installed between the tips of the two anchors 71, and the outer corrugated iron plate 55 is fixed to the furring strip 56. The furring strip 56 is formed of a steel material having an L-shaped cross section, and includes a horizontal portion 57 and a vertical portion 58. The horizontal portion 57 is positioned below the vertical portion 58 so that the bolt 61 and the nut are provided. It is fixed to the anchor 71 by 62.

In this case, no vibration isolator is provided between the horizontal portion 57 of the furring strip 56 and the horizontal portion 72 of the anchor 71, and between the horizontal portion 72 and the nut 62, and a heat retaining structure is provided. It's just Therefore, the vertical thermal expansion of the exterior iron plate 55 can be easily absorbed by loosely tightening the bolt 61 and the nut 62.

The present invention is not limited to the above-mentioned embodiments, but can be variously modified within the scope of the present invention, and they are not excluded from the scope of the present invention.

[0033]

As described in detail above, according to the present invention, the hot gas flows inside the wall structure. Then, an outer wall, an anchor fixed to the outer wall by projecting outward at a plurality of locations, a heat insulating material arranged on the outer side of the outer wall, a furring strip erected between the ends of the anchor, It has an exterior iron plate fixed to the furring strip.

The anchor is made of twisted bar-shaped flat steel twisted near the tip, and
A horizontal portion and a vertical portion are provided, and the vertical portion is disposed in the heat insulating material, and the horizontal portion projects from the heat insulating material and supports the furring strip. In this case, when the heat of the high-temperature gas is transferred to the outer wall and the outer wall thermally expands to expand the space between the anchors, the deformation absorbing part between the horizontal part and the vertical part of the anchor deforms to absorb the thermal expansion. To do.

Therefore, the outer iron plate is prevented from coming off the anchor and the outer wall is not deformed. Further, since the anchor is made of flat steel, the weight is about half that of the conventional one. Furthermore, since only the vertical portion of the anchor penetrates the heat insulating material, the heat insulating material can be easily cut.

In another wall structure of the present invention, a vibration damping material is further arranged between the horizontal portion of the anchor and the furring strip. In this case, since the vibration isolator is provided, it is possible to prevent noise such as a hammering sound generated inside the wall structure from leaking to the outside as vibration noise from the outer iron plate through the outer wall and the anchor. Instead, it is possible to absorb the vertical thermal expansion of the exterior iron plate.
